METHOD OF PRODUCING CRYSTALLIZED GLASS SUBSTRATES, AND METHOD OF PRODUCING DOUBLE-SIDED WIRING BOARD |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a producing method by which crystallized glass substrates having a sufficiently large thermal expansion coefficient can be stably obtained. Ž<P>SOLUTION: The method of producing crystallized glass substrates comprises exposing an ultraviolet ray onto the glass substrates containing as the main component at least SiO<SB>2</SB>, with the exposure energy controlled in the range of 1-20 J/cm<SP>2</SP>, and then heat treating at heat treatment temperature controlled in the range of 780-900°C.
